Does anyone know the sorting algorithms pandora, Netflix, Hulu, and other media use?

Question

I did some research into it, and pandora has their sorting algorithm on patent. I couldn't find anything from Netflix or Hulu, but I would like to know how to implement the algorithm for related categories/genres of art.

Answer 1

thank you

Answer 2

It's more likely to be time decay algorithm that gets the most trending stuff on top while removing the actual need of sorting on likes and dislikes. It gets the stuff that gets most likes in lowest time.
